GPIO set time

[Thangaraj]

NRF52,S132 soft device, I am trying to toggle GPIO 10 (NFC pins Enabled as GPIO)in a 1us Timer, But its not happening , What may be the issue? Am using Timer 4. What is the minimum time taken on GPIO toggling

how do you enable it? did you try using another pin? Just to make sure that the problem is elsewhere. 1us toggling should be easily achieved.
